Research Abstract

Brains of mammalian species mutually differ in the morphology and functions, even those of human and chimpanzee that share~ 98% nucleotide homologies. We have reported promoter-associated noncoding RNA(pancRNA) that acts to activate downstream gene expression through DNA demethylation. This study shows that DNA elements inserted into gene promoter regions of a certain species have provided the templates for species-specific panc RNAs.
